    Description

      We have some tickets for various aspects of UDF (CASSANDRA-4914, CASSANDRA-5970, CASSANDRA-4998) but they all suffer from various degrees of ocean-boiling.

      Let's start with something simple: allowing pure user-defined functions in the SELECT clause of a CQL query. That's it.

      By "pure" I mean, must depend only on the input parameters. No side effects. No exposure to C* internals. Column values in, result out. http://en.wikipedia.org/wiki/Pure_function
